Ad-hoc computer systems can automatically realize higher services when at least two distributed and communicating (embedded) devices come together. For this purpose, they must able to manage appearance and loss of devices and resources, and they have to adapt to changes in requirements and environment. Based on a component-oriented approach for adaptive ad-hoc systems, this paper suggests a high-level service quality reference model to advocate further research on the quality matching problem between service provider and client components.

Dynamic computing systems with small, distributed, and communicating embedded devices, as they are expected for the future, must be able to manage appearance and loss of devices and resources. For the development of static systems, component-oriented engineering approaches have been shown to foster well-structured, configurable systems. Frameworks for the dynamic integration of such components often rely on a centralized component integration platform, containing service brokers and similar. This paper describes several aspects of a component-oriented approach for the development of dynamic-adaptive systems that distributes all needed infrastructure among the participating embedded devices. This results in a runtime framework working whenever two components come together and form an ad-hoc system.
